Application filed February 10, 1923. Serial No. 618,350.

To all whom it may conce-fra:

Be it known that I, JOHN R. BRAZEALE, a citizen of the United States,residing at Ozark, in the county` of Christian and State of Missouri,have invented certain new and useful Improvements'in a Grip Vrench, ofwhich the following is a specification.

The present invention relates to a grip wrench and has for its principalobject to provide a structure whereby the range of the jaws may beeasily and readily adjusted.

Another important object of the invention is to generally improve uponadjustable grip wrenches of this nature by providing a simple andeft'icent structure which is reliable in operation, durable, light inconstruction, inexpensive to manufacture, lattractive in appearance, andwell adapted to the purpose for which it is designed.

lVith the above and numerous other objects in view as will appear as thedescription progresses, the invention resides in cer- `tain novelfeatures of construction, and the combination and arrangement of part-sas will be hereinafter more fully described and claimed.

In the drawing- Figure 1 is an elevation of the wrench embodying myinvention,

Figure 2 is a longitudinal sect-ion taken therethrough substantially onthe line 2 2 of Figure 1, looking in the direction of the arrow,

Figure 3 is a perspective of the xed jaw,

Figure 4 is an edge elevation of the upper portion of the wrench asshown in Figure 1,

Figure 5 is a transverse section taken' substantially on the line 5-5 ofFigure 1, looking in the direction of the arrow, and

Figure 6 is an edge view of the shank structure of the movable jaw.

Referring -to the'drawing in detail it will be seen that the preferredembodiment of the wrench consists of the inain handle 1 upon which isdisposed the` fixed jaw A. The fixed jaw A is formed by having its body2 integral with the shank 3 which in turn is integral with the handle 1and a pair of thickening plates t are disposed one on each side of thebody 2. A rib 5 is disposed on the shank 3 extending transversely `ofthe handle 1.

A movable jaw B is associated with the fixed jaw A and consists of threelayers in the present embodiment which are secured together so that itwill be of equal thickness with the lixed jaw A. The outer layersterminate in extensions formiiiga `shank 7 These extensions of the shankV7are spaced from each other and have teeth 8 arranged on one edgethereof adjacent the handle 1. One of the extensions ,of the' shank 7 isprovided with a groove 9 for receiving the rib 5, itl being understoodthat when the aws A and B are assembled the shank 7 straddlesv the shank3 and the jaws A and B may then be moved toward and away from eachother.

An operating lever C-is fulcrumed at 10 by a bolt o r a rivet or in anyother suitable manner to the handle 1. This operating lever C consistsof a handle portion 11 which is U-shaped in cross section for receivingthe lmain handle 1. The fulcrum portion o f the lever consists of twospaced` extensions one on each side of the handle 1 and indicated by thenumeral 12. The ends of these extensions 12 are provided with teeth 13capable of meshing with teeth S on the shank 7. When the handle 1l ofthe lever C is disposed at an angle of approximately with respect to thehandle 1 the teeth 13 will he disengaged from the teeth 8 and the rangeof the jaws A and B may be approximately set. Asthe handle 11 isfulycruined toward the handle 1 the teeth 13 will engage withthe teeth 8and further fulcruming ofthe handle 11 toward handle 1 will cause themoving of jaw B towardv jaw A for the purpose of gripping a nut or thelike. v

The edge of the handle-1 farthest from the handle 1-1 of the operatinglever C is thickened by a rib 15 disposed on one vside of the handleadjacent the edge and suitably ixed thereto. This rib not onlystrengthens the handle 1 but also prevents the hand from becoming cut orinjured when squeezing the handles 1 and 11 towards each other. It islalso l to bel noted that the U- shaped cross sectional structure of thehandle 11 is formed with the space therein sufficiently small so thatwhen the handle 1 is disposed within the handle 11 there will be acertain frictional 'engagement therebetween so that-the wrench willnormally remain in a closed positionl when situated in a tool boxr or inany other receptacle thereby vpreventing the parts thereof fromaccidentally disasseinbling.

Although I have described my invention with some degree ofparticularity, itis'to be understood that numerous changes in thedetails of construction and inthe combination and arrangement of partsmay be resorted to Without departing from the spirit of the invention ashereinafter claimed.

Having thus described my invention what claim as new is ln a Wrench ofthe class described, a liXed jaw, a movable jaw, said ixed jawconsisting of three plates fixed together, the intermediate plate beingextended to form a shanlg and said shank being extended to iorm ahandle, a rib disposed on the shank and extendingl transversely of thehandle; said movable jaw consisting of three plates, the two outerplates being extended to form Shanks spaced 'from each other to receivetherebetween the shank of the fixed jaw, one of the Shanks of themovable jaw being provided With a groove for receiving the rib on theshank of the Xed jaw, the edges of the shanks of the movable jaw heiligpro vided With teeth; and an operating lever having a pair of spacedextensions pivoted to the handle and terminating in teeth for engagementWith the teeth of the Shanks of the movable' jaw all in the manner andlor the purpose speolied.

In testimony whereof l affix my signaturein presence of two Witnesses.
